capturing the results of d.where -- a intermitant problem!

[Joe Vaughan]

Hello GRASS People,
I am working with a shell script which puts up an image and invites the user to
select a site.  The d.where command is used and the output is placed in a file.
The problem is that I get an error on the stdin ( the mouse button generated
long lat data ), but only sometimes.  This occurs under both of the following
methods of capture:

 1) d.where > file
and

 2) cat > file <<eof
    ` d.where `
    eof

Is there some option to control how sensitive ( robust ) the stdin I/O is for
the mouse?  d.where doesn't seem to have any pertinent options.  What is the
safest way to trap input from d.where?
As always, you help is very much appreciated!
